MEANS FOR REMOVING GUARANTEE-PLATES.

SPEC'IFTGATION forming part of Letters Patent No. 688,481, datedDecember 10, 1901.

Application filed April 8, 190l- To all whom it may concern:

Be it known that we, EDWARD O'lT and ED- WARD B. ENTWISLE, of Y J ohnstown, in the county of Oambria and State of Pennsylvania,

have invented a new and us'efullmprovement in Means for Removing Guarantee-Plates, of which the following is a full, clear, and exact description, reference being bad to the acsecured in a pocket or recess of the foundation structure, are intended to be removed and replaced by new ones when they become such removalwithout disturbing the balance of the structure or the adjacent pavement.

A furtherfobject is to provide means of the 6 character described so constructed that in 5o DandD operation any part thereof whichv would obstruct the passage of a car over that portion of the track-may be quickly removed to permit the car to pass and'then replaced.

Withthese objects inview our invention consistsin thenovel construction, arrangement, and combination of parts, all as hereinafter described, and pointed out'in the ap-' pended claims, reference being had to the aci companying drawings,: in which,

Figure 1 is a perspective View showing a device embodying our inve'ntion an'fdalso the manner of its use, and Fig.2 is a detail view of one of the hook-bolts. Q j

The letter A designates a bar of suitable length having a slot 0., which extends the greater portion of-the length of the bar. an opens outthrough one'end'thereof.

Y B B designate hook bolts, each of which has a threaded shank adapted to pass through the slot or and receive a nut Cupon its upper end portion. I

'are washers which are interposed derneath the plate.

Serial No. 54,779. (No model.)

between the nut O and the upper surface of the bar A. The washer D is different from the washer D in that it is formed with depending ribs or flanges d, which embrace the lateral faces of the bar, and thus keep the latter from spreading at that end through which the slot at extends. Below this threaded shank or bolt B is a comparatively thin flattened portion of greater breadth than thickness, whose lower end terminates in an inwardly-bent hook b, preferably pointed or sharpened at its end.

O designates a track structure, andP an intersection or crossing plate seated therein. The particular structure shown is similar in character to the construction shown in the patent to Moxham, No. 540,796, above mentioned, in which a space is left at the two sides and underneath the plate P for therescribed the spelter or other retaining material is first wholly or partially removedfrom the sides of the plate P and from the recesses'o by cutting or chipping with a chisel or other suit able tool. at opposite sides of the plate P (shown in Fig. 1) in the recesses o, and their hooks bare engagedwith the side of the plate. This may 'bedone bydriving Wedges between the plates and the outer walls of the recesses 0, thus forcing the edges of the hooks inwardly unthe hooks engage the plate is clearly shown in Fig. 1 in which we have broken out a portion of the track structure and of the adjacent pavement in order to show such engage-' 'ment." The bar A is laid across the top of the structure upon blocks R with the threaded shanks of the bolts extending up through the I slot 0.. The nuts and washers are then applied and by means of a track-wrench or other suitable wrench the nuts are screwed down until the plate is lifted wholly or partially The hook-bolts B are then inserted The manner'in which from its seat. In some structures the under side of the plate or the bottom of the plate pocket is provided opposite the recesses 0 with a recess or depression made for the especial purpose of facilitating insertion of a pry-bar or other implement, such recess or depression being filled with clay for the purpose of excluding spelter and which may be readily chipped out. With such structures the hooks b can be made to enter these recesses or depressions and may accordingly be made thicker and heavier than those shown in the drawings.

The slot a in the bar A permits lateral adjustment of the bolts therein for the purpose of adapting them to plates of dilterent widths. he slot a might be closed at both ends; but we preferably leave it open at one end, as above described, in order that whenever it is necessary to permit a car to pass over the structure 0, after the device is applied to the plate, the bar can be quickly removed by endwise movement by simply slacking the nuts 0. If the slot is closed at both ends, it is of course necessary to entirely remove both nuts and washers.

It is obvious that changes may be made in the details of construction herein shown and described without departing from our invention.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1. A device for removing crossing-plates from track structures, comprising a bar, depending hooks carried thereby and adapted to engage the under side of the plate to be removed at opposite sides thereof, and liftingnuts engaging threaded portions of such hooks and having a downward bearing on the said bar, said hooks having shanks of suflicient length to enable the bar to be supported above and clear of the upper surface of the plate.

2. A device for removing crossing-plates from track structures, consisting of a bar adapted to lie across the structure, depending hooks carried by said bar and arranged to engage the under side of said plate through rebar adapted to lie across the structure, hookbolts arranged to engage the under side of the plate to be removed through recesses in the said structure and having threaded shanks extending through the said slot and laterally adjustable therein, and lifting-nuts on the said shanks, the shanks being of sufiicient length to enable the bar to be supported above and clear of the upper surface of the plate to be removed.

4:. A device for removing crossiug plates from track structures, consisting of a bar adapted to lie across the track structure, a pair of laterally-adjustable hooks carried by said bar and movable vertically therethrough, and lifting-nuts on the shanks of said hooks having a downward bearing against the said bar, said hooks having shanks of suflicient length to enable the bar to be supported above and clear of the upper surface of the plate.

5. A device for removing crossing-plates from track structures, consisting of a bar adapted to lie across the track structure, a pair of laterally-adjustable hooks carried by said bar and movable vertically therethrough,

lifting-nuts on the shanks of said hooks having a downward bearing against the said bar, and means for effecting the removalof the bar from the said hooks by endwise movement.

6. A device for removing crossing-plates from track structures, consisting of a bar having a longitudinal slot extending through one end thereof, hook-bolts having threaded shanks extending vertically through the said slot and laterally adjustable therein, and lifting-nuts on the said shanks having a downward bearing on said bar.

7. A device for removing crossing-plates from track structures, consisting of a transverse bar having a longitudinal slot extending through one end thereof, hook-bolts having threaded shanks extending vertically through said slot and laterally adjustable therein, lifting-11 uts on the said shanks, and washers interposed between the said nuts and the upper surface of the bar, one of such washers having flanges which embrace the sides of the bar at its open end.

In testimony whereof we have affixed our signatures in presence of two witnesses.
